Based upon such evaluation, at June 30, 2018, we were not party to any pending legal or administrative proceedings that may have a material adverse effect, either individually or in the aggregate, on our business, financial condition or results of operations.

We were required to make payments under a certain channel distribution agreement if revenue targets are achieved. The maximum amount of such payments was $0.5 million, which was accrued as of December 31, 2017, and was subsequently paid in April 2018.
